AUTOMATIC GRAIN-SCALE.

SPECIFICATION forming part of Letters Patent No. 362,992, dated May 17,1887. i Application filed September 16,1886. Serial No. 213,746. (No model.) v

To all whom it may concern:

Be it known that I, FEDER O. PEDERsoN, a citizen oftheUnited States, residing at Albion, in the county of Jackson, in the State of Wisconsin, have invented certain new, useful, and important Improvements upon a Machine for Automatically Weighing and Registering Grain, which may be used upon a thrashingmachine or in an elevator or grain'ery,of which the following is a specification.

Figure 1 represents an external appearance of the machine; Fig. 2, an end elevation in section, and Fig. 3 a side elevation of the interior thereof.

The registering mechanism is within the boX ct. Grain enters the machine through the funnel b. On the frontend of the box are openings in a. hinged door, which can be swung open by unlatching the hook c, which it is necessary to do in order to reset the registering wheels Through these openings are seen the iigures upon the registeringwheels d d2 d, representing units, tens, and hundreds. The seale-beam f projects through the top of the box near its front end. This beam has a movable weight, f2, that, when adjusted thereon to the figures showing the quantity of'grain to be weighed in each bin, is secured in place by the set-screw 3. Whenever the scale-beam swings from one side of the box to the other, as shown by dotted lines i-n the drawings, Fig. 2, a pawl, g, moves the unit wheel forward one tooth. Spring -paw1s 2 3 4 prevent any backward movement of the wheels d d2 d,- but as thereis no novelty in the registering mechanism it will not be further described. v

There are two V-shaped grain-bins, h h2.

A They slide in grooves in the vertical supports 7c k2 on either side of the bins. These balanced bins are suspendedV from the oscillating shaft m by means of ropes n, which are fastened to the half pulley-wheels o o2, that are rigidly secured to and turn with the shaft. The inside of each bin, at the bottom, has an opening, p, which corresponds in shape to the opening p2 in the partition between the bins. The emptied grain falls into a chute, q, and thenceinto measures; or bags may be hung upon the rollers r r2 by means of the pins 5 6. These rollers are connected together by a crossed rope, s, and are turned partly over by the levert, which movement lets the bags be disengaged easily from the pins.

When the grain enters the hopper underneath the funnel, it falls upon the spout u, rigidly attached to the oscillating shaft fv. This shaft is turned by means of the pin w on the half pulley-wheel 02, working in `the forked lever zo.

The operation is`as follows: Vhen a bin is full or has the number of pounds of grain in it indicated by the scale-beam, it sinks down and discharges itself, turning the main shaft m and raising the empty bin. The turning of the shaft shifts the position of the scalebeam. The pin w on the half pulley-wheel Withinthe forked lever wl turns the shaft o, changes the position of the grain-spout u, and causes the grain to flow into and iill the empty bin.

VVh'at I claim as new, and desire to secure by Letters Patent, isl. The combination of the two bins h h2 with the oscillating shafts mo and the scale-beam upon the shaft m, as described.

2. The combination of the shafts m o with the scale-beam f, half-wheel o2, and the pin and forked lever w yw?, substantially as described.
